Designation: A 580/A 580M 06 Standard Specification for Stainless Steel Wire 1 This standard is issued under the fixed designation A 580/A 580M; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (e) indicates an editorial change since the last revision or reapproval. This standard has been approved for use by agencies of the Department of Defense. 1. Scope* 1.1 This specification covers stainless steel wire, except the free-machining types. It includes round, square, octagon, hexagon, and shape wire in coils only for the more commonly used types of stainless steels for general corrosion resistance and high-temperature service. For bars in straightened and cut lengths, see Specifications A 276 or A 479/A 479M. NOTE 1 For free-machining stainless wire, designed especially for optimum machinability, see Specification A 581/A 581M. 1.2 Unless the order specifies the applicable M specification designation, the material shall be furnished to the inchpound units. 1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. 2.

4.2.1 Cold Drawn A finish resulting from a final cold drawing pass, generally with cold drawing lubricant left on. Special bright finishes, lubricant removal, etc., for special end uses must be negotiated with the producer. 4.2.2 Annealed and Pickled A dull matte appearance necessarily associated with the dead-soft condition when no final cold drawing is permitted. 5. Chemical Composition 5.1 The steel shall conform to the requirements as to chemical composition specified in Table 1. 6. Mechanical Requirements 6.1 The material shall conform to the mechanical test requirements specified in Table 2. 6.2 The martensitic grades shall be capable of meeting the hardness requirements, after heat treating, as specified in Table 3. 7. General Requirements for Delivery 7.1 In addition to the requirements of this specification, all requirements of the current edition of Specification A 555/ A 555M shall apply. Failure to comply with the general requirements of Specification A 555/A 555M constitutes nonconformance with this specification. 8.
